On April 25th the 4th tracker arrived! (yay)But no, same error to my disappointment.

I spent almost 5 hours, removing USB drivers, restarting and trying every combination of 4 dongles and 4 trackers.

Through experimentation I have discovered that I have two dead Vive Tracker Dongles.

There are 2 dongles that never worked with any of the 4 trackers. These dongles are DOA and do not work. (I tested these two dongles all four trackers, they had terrible tracking quality and most importantly: caused the 10016 error)

I would like request help in getting replacements for my dongles, thank you!

I also have 3 trackers, tried all of the steps written in the previous message + instructions in the link at the bottom, and I found that one of the tracker usb dongle is the source of the problem.

I've contacted HTC, but they say that I would have to send back the unit (instead of replacing) even though I bought it in March, been in touch with them from beggining of April, and the thing never worked since I opened the package.

I am willing to pay for another tracker+dongle pair, or for just the dongle, but at the moment, I'm out of options.
